Multi function water pump control valve
Structure and use:
The valve is mainly composed of a main valve 1, a regulating valve 2, a filter 3, etc. The water supply and drainage system of industrial and mining enterprises and high-rise buildings directly by water pumps has four functions: stop valve, check valve, electric valve and water hammer eliminator. It is especially suitable for supporting automatic water lifting control system. It does not need electrical controller and external power. It can be opened and closed automatically according to the conventional method. It has three functions of preventing and eliminating water hammer, namely, quick closing, slow closing and energy absorption chamber, which can effectively improve the safety and reliability of the system. Meet the requirements of automatic control of system engineering equipment.
